Granted: 1992-04-07
Abstract: ABSTRACT OF THE DISCLOSURE        An  improved  seal  element  for  use  with  a  self contained  recreational   vehicle  sanitary   system.   This invention is particularly adapted  for use with  the type of sanitary system having  a bench  structure which  defines an interior  storage  compartment  and  a  waste  holding  tank removably  disposed  in  the   storage  compartment.   Waste products are  transferred from  the  bench structure  to the waste holding tank  via a fill  opening.  A  seal element is disposed around  the  perimeter of  the  fill  opening which seals against both the  bench structure and  a movable blade valve mounted within the  holding tank which  closes off the fill opening when it  is desired to remove  the holding tank for dumping  etc. The  seal  element includes  one  or more sealing lips  which engage  the  valve blade  member  in its closed position.   One of  the seal  lips  is disposed  in a generally   radially  outwardly  projecting  direction  with respect to the fill opening when  the valve is closed.  This seal lip  is  self  actuating since  it  more  tightly seals against the valve blade in response to internal hydroplastic pressure thus providing superior  protection against leakage of the contents of the waste holding tank.

Abstract: DUPLEX OPTICAL FIBER CONNECTOR     Abstract A duplex optical fiber connector includes a housing having a cable entrance end and a plug end. At the cable entrance end, an optical fiber cable which includes two individually buffered optical fibers, strength member yarn and a plastic jacket is routed into a flanged end of a bushing having a tapered passageway therethrough. The bushing is supported in a base of the housing. The jacket is removed from the portion of the cable which extends from the cable entrance end to the plug end and the yarn is positioned between two conformable, truncated conically shaped, substantially smooth surfaces which define the passageway of the bushing and a truncated conically shaped wedge which is received in the passageway. The wedge includes a bore through which the optical fibers extend. This locking arrangement in which the yarn makes no retroflexed turns is self-enhancing when tensile forces are applied to the cable. At the plug end are secured two plugs each terminating one of the optical fibers. Each plug is spring-loaded and further, end portions of the plugs which protrude beyond the connector housing are protected by a bumper which also is spring-loaded and which is moved inwardly when the connector is assembled to another. A cover is assembled to the base to complete the housing and to secure the force-transfer facilities and plugs therein.

Title: Automatic pressurized reservoir bleed valve
Inventor: SILVERWATER BERNARD F
IPC: F15B21/044
Filed: 1988-04-05
Granted: 1991-10-15
Abstract: Abstract:       An automatic bleed valve for bleeding air from a pressurized liquid reservoir or, with reversal of principal elements, bleeding liquid from a compressed gas reservoir comprises a piston in a piston chamber located in a flow passage leading from the reservoir.  A capillary passage is provided through the piston, and the piston is urged upstream by a resilient spring.  An orifice is located in the fluid channel.  A sealing element is provided at the downstream end of the piston chamber.  Upon activation of the hydraulic system while air is being expelled from the reservoir, the resilient spring will retain the piston in the upstream position, allowing gas to be bled from the reservoir through the fluid passage in the piston.  When liquid begins to flow from the reservoir, the pressure differential over the piston increases, causing the piston to move against the downstream end of the piston chamber and seal off the fluid channel and the hydraulic reservoir.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of adjusting a thermal balance of a rotor.  When obtaining a difference in shaft-vibration component of the rotor between an actual load condition and a no load condition, on the basis of detection results at a simulated load, a difference in shaft-vibration component of the rotating rotor between a no-load condition and a condition in which the rotor is heated from the outside and a difference in shaft-vibration component of the rotating rotor between a no-load condition and a condition in which the rotor is heated from the inside are detected at the simulated load.  The detected differences in shaft-vibration component are converted respectively to differences in shaft-vibration component under a temperature condition at the actual load.  Both the converted differences in shaft-vibration component are added to each other in a vector manner to obtain a difference in rotor shaft-vibration component at the actual load.  Coolant flow rate at each section within the rotor is so adjusted as to eliminate the difference in rotor shaft-vibration component, thereby adjusting the thermal balance of the rotor.
